Capacitively coupled level shift circuit of small size and low power consumption

摘要

The present invention relates to a level shift circuit. The level shift circuit, connected in series with the first transistor between the input signal from the input port is applied to a gate, a first transistor having a first polarity and a negative power supply and positive power supply , and a second transistor having a second polarity is opposite polarity to the first polarity, an inverter, an output port connected to the connection node between the second transistor and the first transistor, wherein a gate of said first transistor a capacitor connected between the gate of the second transistor, using the output port signals of the inverter and the clock signal, and is applied to the gate of the second transistor by a precise switching operation time of the second transistor I include a voltage adjusting means for adjusting the exact voltage. As well as a possible high-speed operation and stable relatively small, it is possible to achieve low power consumption.
